Diagnostics connection
The diagnostics connection is used for connect- ing diagnostic equipment at a qualified special-
ist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result, the operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec- tion. Qualified specialist workshop
A qualified specialist workshop has the neces-
sary special skills, tools and qualifications to
correctly carry out any necessary work on your
vehicle. This particularly applies to work rele-
vant to safety.
Observe the notes in the Service Booklet. Always have the following work carried out at a
qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conversions
R work on electronic components
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres to
carry out technical inspections on certain vehi-
cles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about vehi-
cle checks if it has your registration data.
It is possible that your vehicle has not yet been
registered in your name in the following cases:
R if your vehicle was not purchased at an
authorised specialist dealer
R if your vehicle has not yet been inspected at a
Mercedes-Benz Service Centre
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle owner-
ship. You can do this at a Mercedes-Benz Ser-
vice Centre, for example. Correct use
If you remove any warning stickers, you or oth-
ers could fail to recognise certain dangers.
Leave warning stickers in position.
Observe the following information when driving
your vehicle:
R the safety notes in this manual
R the vehicle technical data
R traffic rules and regulations
R laws and safety standards pertaining to motor
vehicles Implied warranty
! Follow the instructions in this manual about
the proper operation of your vehicle as well as Operating safety
